The shaft 14 is rotatable on its axis and whenthe shaft is rotated, the pinion 15, cooperating with the rack 7 will Vcause the base plate 1 and parts`carried thereby to move in an orbit, in a way well understood by those skilled in the art.

In Figures 4, 5, and 6 parts hereinbefore described and designated by numerals previously used with the suiX a. In this form of the yinvention the marginal rib 4a is a separable 'member whereas the rib 4 of Figure 2 is Jformed integrally with the table,

'Ihe struc- `regnare curing elements connecting the bar and the cover plate with the lug, the cover plate extending into the ring and having its outer surface flush with the outer surface of the ring, a shaft movable in the groove, and between the-outer edge of the cover plate and the inner edge of the ring, and a pinion on the shaft, the pinion being extended between the ring and the table, and between the lug and the cover plate, the bar and the rib constituting constituent portions of the gearing, and one of said constituent portions having a rack wherewith the pinion meshes.-`

ture, furthermore, is such that the parts 4a V and 6 may be made out of a better gradeof material than the "rest'ofthe deviceand this is desirable, because the parts 4a and 6:carry the'racks which must bear the wear resulting from the actionofthepinions 15-15a. The

shaft 14, taken as typical, has/a good bearing inthegroove andV inthe slot. The pinion. 15 is sustained, laterally, to a desirable -*and satisfactory: .extent because `it projects between the table 5 and the cover ring IO-and between the cover plateS'and thelug s The generalconstructionis such that accessmay be had to alll working parts by removing the securing elements, such 1 as the bolts 9-11.
